I have a Blackberry 8100 on Orange UK. Up until recently I used BIS. I chnaged my account to a business account and now have BES enabled on my SIM. I have phoned to check BIS is off and BES is on. Although, Orange didnt seem too knowledgable.

I can get the phone to work, send / recieve email / calender etc but only when connected to the BES via USB. It wont activate wirelessly or send / recieve. I get the red X and Message Status: Service blocked.

I have wiped the Blackberry several times now as I thought the old BIS services may have still been on it.

I am no expert on this at all but my gut instinct tells me Orange havent got my account setup properly.

Is there anything you guys / girls could suggest for me to try before trying Orange again?
